Union Among the Churches of the Anglican Communion - Encyclical Letter 1.7: Of common work
Believing that the unity of our Churches will be especially manifested and strengthened by their unity together in common work, your Committee would call attention to the great value of such co-operation wherever the opportunity shall present itself; as, for example, in founding and maintaining, in the missionary field, schools for the training of a native ministry, such as that which is now contemplated in Shanghai, and, generally, as far as may be possible, in prosecuting missionary work, such as that which the Churches in England and Scotland are maintaining together in Kaffraria.
[NOTE: The Lambeth Conference of 1878 did not adopt any formal Resolutions as such. The mind of the Conference was recorded by incorporating the Reports of its five Committees, received by the plenary Conference with almost complete unanimity, into an Encyclical Letter which was duly published. Recommendations embodied in the Committee Reports were evidently accorded equivalent status to formal Resolutions, and they are reproduced here as they appeared in the course of the Encyclical Letter, under appropriate reference.]
